What should I look for when choosing an entrance door?
Durable steel construction that can withstand blunt force, design flexibility for your façade, and verified compliance with recognised industry standards.
Are GIESTA entrance doors burglar-resistant?
Yes — a triple sickle-shaped latch system, double lock mechanism, concealed hinges, and steel-reinforced panels are built in as standard, with a removable thumb-turn key for added security.
Is a GIESTA door made of wood or steel?
Steel — the wood-grain look comes from a TEXGUARD-coated finish applied over the steel panel, combining a timber aesthetic with steel-level durability.
How long does the finish last?
TEXGUARD coating holds its gloss and colour for up to 40 years, without warping, rusting, or deforming under normal use.
Can I add sidelights or glass panels?
Yes — single or double sidelights and glass elements can be added, along with a choice of in-swing or out-swing configurations.
